Rycina: Shell of gastropod Desbruyeresia marisindica from Kairei hydrothermal vents in the Indian Ocean, covered with inorganic coatings (A), with cross section through this shell showing morphology of inorganic coatings (B) and close-up on a fragment showing structure and shell/coating spatial relations (C). Distribution of some elements (oxygen, manganese, calcium, iron, copper, and phosphorus) in a fragment of coating illustrated in (C) is shown in lower two rows.

Radiospherid (spinose) calcispheres with highly mineralized mucous envelopes around single-celled algae. Scale A the same for B and D. The central chamber of the calcisphere is typically between 30 and 50 µm.

Figure: Variability in temperature measured in different species of rudist bivalves (upper plot) and well preserved specimen of Vaccinites vesciculosus (lower photo). Coloured violin plots indicate the spread in the full dataset, while black symbols indicate monthly mean values. Grey horizontal lines show the highest and lowest monthly mean value, respectively, through the entire dataset.

Polska Akademia Umiejętności to jedna z najbardziej prestiżowych instytucji naukowych w Polsce, której historia sięga 1872 roku, kiedy to powstała jako Akademia Umiejętności z inicjatywy grona wybitnych uczonych i zatwierdzona przez cesarza Franciszka Józefa. Po II wojnie światowej jej działalność została ograniczona, jednak w 1989 roku dokonano jej pełnej reaktywacji, co pozwoliło przywrócić jej dawną pozycję w środowisku akademickim. PAU jest nie tylko instytucją naukową, ale także strażnikiem polskiego dziedzictwa intelektualnego, m.in. jest właścicielem Fototeki Lanckorońskich oraz współwłaścicielem bezcennej Bibilioteki Polskiej w Paryżu. Jej misją jest rozwój nauki na najwyższym poziomie oraz popularyzacja wiedzy wśród szerokiego grona odbiorców. https://pau.krakow.pl/index.php/pl/struktura/wydzialy-i-komisje/wydzial-iv-przyrodniczy
Z przyjemnością informujemy, że podczas Uroczystego Posiedzenia Naukowego Polskiej Akademii Umiejętności, które odbyło się 15 listopada, prof. Jarosław Stolarski, dyrektor Instytutu Paleobiologii PAN został uhonorowany godnością członka korespondenta Wydziału IV (Przyrodniczego).

A taxonomic revision of the extinct genus Zittelia from Jurassic sediments made it possible to trace a gradual evolutionary change in shell morphology: from the earliest species with an oval shell and elevated spire to later ones with a more globular form, in which the spire scarcely rises above the last whorl. The morphology of the aperture indicates an affinity of Zittelia with representatives of the cowries (superfamily Cypraeoidea), whose earliest members likewise appeared in the Late Jurassic.
